4.0 Commands
4.10 – 4.11
4.10
SELECT DUTY
This command is used to select the duty (degree of multiplexity) of LCD driving. It is valid for the
SED1520F (actively operating LSI) only, not valid for the SED1521F (passively operating LSI).
The SED1521F operates with any duty determined by the FR signal.
D = 0:
D = 1:
Duty 1/16
Duty 1/32
If the system contains both SED1520FOA (internal oscillation) and the SED1521FOA LSIs, they
must have the same duty.
4.11
READ MODIFY WRITE
This command is used with the End command in a pair. Once it has been entered, the column
address will be incremented not by the Read Display Data command but by the Write Display Data
command only. This mode will stay until the End command is entered.
Entry of the End command causes the column address to return to the address which was valid
when the Read Modify Write command was entered. This function lessens the load of the MPU
when the data in a specific display area are repeatedly updated (as blinking cursor).
Even in the Read Modify Write mode, any command other than Read/Write Data and Set Column
Address may be used.
